This is the kit for a proper primary bathroom shower — 48" × 72" gives you a long, open rectangular footprint with room for a bench, a rain head, or just the luxury of not feeling cramped. If your client is upgrading a master bath, this is the size that actually delivers on the "spa-like" promise.

Includes the KERDI-SHOWER-T pre-sloped foam tray, full KERDI waterproofing membrane roll for walls, KERDI-BAND strips for seams and corners, and hardware. Choose your KERDI-DRAIN separately based on finish preference.

Why the pre-sloped tray matters more at this size

On a 72" long floor, getting a hand-floated mortar bed to slope uniformly to a center drain without low spots is genuinely difficult — even for experienced tile setters. The KERDI-SHOWER-T has the slope engineered in at the factory. You're not trusting your float job; you're trusting Schluter's tooling. At this size, that's a meaningful quality assurance advantage.

What it pairs with

• Drain options: Standard center-drain KERDI-DRAIN body + Classic stainless or Trendline grate kit
• Upgrade idea: Pair with KERDI-SHOWER-LT (linear tray) if your client wants a wall-to-wall drain and large-format tile — the flat single-plane slope makes 24"×24"+ tile much easier
• Bench: KERDI-BOARD-SB prefab bench integrates into the system waterproofing seamlessly
• Niche: At this length, two KERDI-BOARD-SN niches work well — one each end wall
• Profiles: JOLLY or RONDEC on any outside tile edges at the shower entry

Pro Tips

• For tile 12" × 24" or larger on this tray, consider 3/8" to 1/2" back-buttering in addition to trowel lines — large format needs maximum coverage to handle the four-plane slope without lippage
• The 48" × 72" tray can accommodate a bench in one corner — plan the bench position before tiling so it integrates with the waterproofing layer properly
• Mark your no-heat zones now if adding DITRA-HEAT: stay 2" from walls and 4" from the drain, and don't run cables under a fixed bench
• Pre-plan your tile layout on paper — at 72", running a 12" tile produces an even 6 tiles with no cuts. A 24" tile = 3 even rows. Work with your tile size, not against it
